Molecular iodine complexes with aromatic compounds

Dependence of spectral properties of iodine molecular complexes with diverse benzene derivatives on ionization potentials of donor molecules was discussed, relying on the experimentally obtained and published data on position of transition bands maxima after iodine complexes charge transfer. It is shown that existence of the complexes isomers is dictated by the structure of the electronic level interacting with the acceptor orbital and spatial structure of the donor molecules
